There are two bugs in this report.

The first bug is When you try doing any type of "/fill" command and you start putting the coordinates in, the game on ps4 will either crash or it will hashtag the whole command out, and I have done the "/fill" command in the chat and in a command block and it still keeps bugging out.

The second bug is when you ad EDU edition to the realm or world, and you do the following commands (/ability @a mayfly true), it does not work the way it use to, it use to work like you could fly in survival but now if I give it so some one in survival and they try to fly, they look like they are being teleported and then dropped and they take fall damage over and over again until it kills your or the person that has it, and the if you do (/ability @a mayfly false) no one will be able to fly even if they are put in creative.
